Stationary and moving UFO in Illinois

Summary

In this 1965 report, a witness in Rivergrove, Illinois, describes an object that appeared stationary but moved from east to west, following an aircraft. The testimony is confusing, as it mentions the object was observed for three days, yet it appeared suddenly in the sky. The Air Force requested more information from the witness, who completed a detailed form describing the object's appearance, trajectory, and weather conditions. The report includes contradictory details, such as the object's size compared to everyday items and the absence of optical instruments used.

The testimony was provided by a civilian who observed the phenomenon from their location, without using telescopes or binoculars. The Air Force officer highlighted the need to clarify certain points, such as whether the object disappeared instantaneously or gradually. Despite the doubts, the witness was considered reliable, and the report ends with questions about possible meteorological or astronomical conditions that could explain the sighting.
